progress bar

[NewCLAD]

y want to show a status bar who will be closed after the operation. The operation is a flashing in memory who is done by a DLL function called in labview VI.

Thank you for your help!!!!and have a nice christmas

LabVIEW 6.1 has various progress bar displays for the front panel under Controls -> Numeric.

Create a property node for the progress bar display you are using.
And set its Visible property to true at the start and to false at the end

the only uncertain is how you will know how much of the "flashing of memory" has occurred.
Is it a set time?

Most FLASH programming tools/software return a value that can be used for progress. Usually it is the number of bytes programmed thus far. Some (like Tornado VisionClick) allow functions to program in smaller steps (within a loop). In that case, you can provide a value to a progress bar.

So there might be some math involved.

I suppose that you can get an estimate of the time required to flash your ROM from the size of the code.
Then you can start a parallel loop to move a progress bar. Use a time slightly larger than your estimate. Stop the loop when the flash is finished.

See the attached vi

You could also run a dedicated vi dynamically, but that's another story ! 🙂

Merry Christmas and Happy Wiring

Hi, happy new year to everyone!!!!
I need to modify a Configuration Setting file and for that I use the VI: Write Characters to file.vi available in the function panel but the problem is that the new file generated has a size of 1.83Kbytes instead of 1.81Kbytes despite the fact that this two files had exactly the same contents
I remenber you that I use Labview7.0.............Thank tou very much and best regards

Probably better to post your question again... Nobody will go down here to help you !
May be you could attach both files in a zipped archive. Somebody could have a look and tell you were is the difference (if any...)

Happy New Wires !

On a side note, I do vaguely remember someone pointing out before that each bend in a wire on the block diagram of a VI takes up space. I believe it was 32 bytes. Sorry if I can't remember who posted the information originally, but I certainly do know I've been avoiding wobbly lines ever since.

Maybe you have the same functions and VIs on the block diagram, but some of the wires have been bent, moved or changed.

Hope this helps

Shane.

Say what?? you mean a simple bend in the wiring takes up 32 bytes.... each?? -wow-
So much for making the wiring look like a circuit card.. 😉

This is good information to post. Maybe we should start a thread called "LabView: Behind the scenes" where we put tid-bits of info like this.

Thanks Shane & Happy New Year.
